One thing to look for is the attribute munging when Exchange 2000
environment on Windows 2000 AD to Windows 2003 upgrade takes place.
Otherwise, seems like a good approach.  There's a kb about adprep and an
Exchange fix for it.

http://www.MSExchange.org/


I am looking at migrating from Win/Exchange 2000 to 2003 later this year.
Does anyone have any best practices or any gotchas I should look for?  I am
going to be attempting it first in a test-bed (obviously) then out on
production machines.  The migration will occur on new hardware, so doing an
in-place upgrade will most likely not happen (though it might at a remote
office or two).  I have read this article
<http://msexchange.org/tutorials/Upgrade_Exchange_2000_to_2003.html>
http://msexchange.org/tutorials/Upgrade_Exchange_2000_to_2003.html, but am
curious what anyone who has done might be able to contribute.  My idea was
to setup a new DC on 2000, do an in-place upgrade to 2003.  Then subsequent
DCs be installed with 2003  After setting up a 2003 server (non-DC) install
Exchange 2003 and move the mailboxes over to the new box.  Is that a good
approach?  I have heard that you can have two Exchange servers and quarterly
upgrade the non-used box with the latest patches and then move mailboxes to
it.  That'll defrag the DB and clean out orphan emails, etc.  A good
approach?

 

TIA for the advice,

 

eric
